DIN50021 Salt Spray Corrosion Test Chamber 120x100x50 B-SST-90 lab Machine

Use:

This machine has a standardized test method to check corrosion resistence of coated samples. Salt spray test is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability in use as a protective finish. The appearance of corrosion products (oxides) is evaluated after a period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion. Different coatings have different behaviour in salt spray test and consequently, test duration will differ from one type of coating to another.

Design Standards:

• Approach:

1. Install the internal parts of the salt spray test chamber: tower spray device, funnel, round rod, V-shaped sample rack, etc.

2. Connect the air source, turn on the power switch after the power supply is connected.

3. Add water in the pressure barrel and the box, stop adding water after the two low water level lights are off, and add water to seal the sealing groove.

4, the purified water and sodium chloride salt in a ratio of 1:20. Pour the prepared solution into the test inlet (turn off the light of low salt water).
